AlFlEtATUS FOR STOPPING TRAINS.

Application filed December 22, 191%.

To all whom 7'7 may concern:

lie it known that l, Domenico l lvxx enir is'rx, a subject of the King of Italy, rcsidinp; in the borough o1 Manhattan, city of New York, and State ot New Yoi'l-r. have invented certain new and use'ti'd Improvements in Apparatus for Stepping Trains, of which the following is a specification.

My invention relates to systems for stopping trains, both electric and steam, and has for its main object to provide improved means whereby trains at crossings and on the same. track will be prevented automati- -allv from collision.

My invention also embodies certain minor details of construction in the apparatus vfor accomplishinggthe main object of the invention. as will be hereinafter more definitely pointed out and claimed, reference being had to the accompanying drawing, in which Figure 1 is a diagrammatic plan view of a railway track crossing, showing my improved train stopping apparatus in operative position in respect thereto.

Fig. 2 is an enlarged detail planview of the circuit breaking apparatus and its operating parts. i

Fig. 3 is an enlarged detail plan view of the air-brake setting mechanism and its operating parts.

Similar numerals of reference denote corresponding parts in the several views.

In the said drawing, and referring more particularly to Fi". 1, the reference numerals 1 indicate the rails of a railway track, and 2 the rails of a similar track crossing the tracks 1 at an angle thereto. The lines formed by the. tracks 1 and 2 will be equipped similarly with my improved train stop-ping apparatus, and a description of one of the same willbe understood to apply equally to the other. Thus, between tracks 1 to the left is a base plate 3, upon which is pivoted at 4 a cross trip ping lever .5, having a projection 6 thereon, adapted to be contacted with by a suitable tripper on the engine of a train moving from left to right, said lever 5 being normally retracted to the position shown in Fig. 1 by a suitable coiled spring 7, and being adapted to be moved at its free end toward the right by the action of the trip- Specification of Letters Patent.

per. .i ivoted to said lever i'i a connecting piece 8, to which a rod 9 is fixed, the. latter being controlled in its longitudinal movement by a guide 10 on the base plate crank 13, the other arm of which is pivoted to a rod 11 running between the tracks .2. The outer end or said rod it is in the path of the end 15 of a ii-shaped plate 143, slotted at 17 to engage a pin 18 fixed to base plate 19, and normady retained in theposition. shown in Fig. 2 by a spring 16 disposed between abutments on said plate 16 and the base plate 19. Said plate 16 when in the position shown inl igs. 1 and 2, contacts with two terminal plates 20, which are in the circuit supplying the current to the tracks 2, a portion or the circuit being shown in dotted lines.

(lust in front of the base plate 19, pivoted at 21, is a bell-crank 22, slotted at '23 to engage a pin 21- on the rod 11, the other end of said bell-crank having pivoted thereto a lever 25, slotted at 26 to engage a pin 27 on the rod 11, said pin 27 and lever 25 being connected by a retracting spring- 28.

The rod 11 extends across the crossing beyond the bell-crank 13 and is in alinenient. with a head 29 fixed to a lever 30 pivoted at 31, and at its opposite end connected by a rod 32 with a bar 33, that in turn connected to a lever 34, pivoted at 35 to a base plate 36, and provided with a projection 37 at its free end, said lever be ing normally retained in the position shown in Fig. 1 by a spring 38.

The operation of these portions of the apparatus is as follows :A train moving from left to right on the track 1, will, in passing over the lever 5, and by contact of its tripper with the projection 6 thereon,

swing said lever 5 on its pivot 4 to the LQQEASQ with the terminal plates 20, thereby brealo side, and the resetting mechanism carried ing the electric circuit to tracks 2, and by plate 36 will also be duplicated upon the causing the stoppage of any train approachopposite side, so that the system will operate ing on said tracks while a train is passing for trains running in both directions and on so on tracks 1 over the crossing. After the both tracks.
